kinship2_alignped4: Compute optimal horizontal spacing for pedigree alignment

In ggpedigree: Visualizing Pedigrees with 'ggplot2' and 'plotly'

Compute optimal horizontal spacing for pedigree alignment

Description

This is an internal helper function for pedigree alignment. It uses quadratic programming to find optimal horizontal positions for subjects that minimize the distance between parents and children while keeping spouses together and respecting spacing constraints. Requires the quadprog package.

Usage

kinship2_alignped4(rval, spouse, level, width, align)

Arguments

rval	Aligned pedigree structure from previous alignment steps
spouse	Logical matrix indicating spouse connections
level	Integer vector of generation levels
width	Numeric, maximum width of the pedigree plot
align	Logical or numeric vector. If logical, uses default alignment parameters. If numeric, should be a vector c(a1, a2) where a1 controls parent-child penalties and a2 controls spouse penalties

Value

Matrix of optimized horizontal positions for each subject
